In his 1959 novel Starship Troopers (the movie of the same name has almost nothing in common with the book--ignore it!), Robert Heinlein invented the idea of powered battle armor, which gave an infantryman more fighting power than a modern tank, protected him from battlefield hazards, allowed central command to locate him and monitor his vital signs, and even dispensed medical treatment.
The idea has become a cliché of computer games, but it's always remained science fiction. Last week, though, the U.S. Army announced it is giving the Massachusetts Institute of Technology $50 million to establish the Institute for Soldier Nanotechnologies, whose primary goal is to develop a new battle suit for special forces that would "heal them, shield ...

The recent announcement that the University of Alberta has landed a $120 million nanotechnology research facility was mostly reported as an example of how the federal Liberals are trying to woo Albertans. Surprisingly little was said about nanotechnology itself (one commentator, in fact, referred to it simply as "nanotechnology--whatever that is.")
Allow me to rectify that.
Nanotechnology is technology that operates on a scale measured in nanometres--billionths of a metre, or if you prefer, a millionths of a millimetre.
The ultimate goal ...

One of the first science-fiction movies I can remember seeing was Fantastic Voyage, in which a submarine and its crew are shrunk to microscopic size and injected into an injured man. Their mission: to vaporize a life-threatening blood clot in his brain. Among other things, the movie featured Racquel Welch in a wetsuit.
In a way, this science fictional vision came a step closer to reality this week when researchers at Cornell University announced they had successfully mated tiny metal propellers with organic molecules, creating ultramicroscopic machines--although they do not, alas, contain itsy-bitsy Racquel Welches.
The propellers don't have any practical application, but they point they way to the day when microscopic devices could harvest medicinal ...

My roommate in university had a quirk that annoyed teachers no end: he had the smallest handwriting of anyone I've ever met. While I used big old Bic pens on wide-lined notebook paper, he was using fine-point mechanical drafting pencils on the narrowest-lined paper he could find, and still leaving lots of room for any corrections he might want to make.
Well, he must have really appreciated last week's announcement in Science magazine that researchers at Northwestern University in Chicago have invented the world's smallest pen. It works essentially the same as the 4,000-year-old dip pen (i.e., a pointy stick dipped in ink), but can draw a line only one molecule deep and only a few dozen ...

One of the first science-fiction movies I can remember seeing was Fantastic Voyage, the tale of a group of scientists in a submarine who were shrunk to microscopic size and injected into the body of an injured man. Their mission: to vaporize a life-threatening but inaccessible blood clot in his brain. Among other things, the movie featured Racquel Welch in a wetsuit.
Believe it or not, this particular science fictional vision might someday become possible--although the machines injected into people's bloodstreams would not contain itsy-bitsy Racquel Welches. In fact, someday machines may be made so small that they could manipulate matter one atom at a time. Since they would operate on the "nanometre" level--a nanometre is one-billionth ...
